Using Microorganisms Flashcards
Fungi used for
Food production
Types of microorganisms
Protozoa
Fungi
Bacteria
Viruses
Bacteria used for
To make human proteins in their genetically modified form
Eg human insulin
Viruses used for
Used in the process of genetic modification
Yeast used in
Production of beer
Produces carbon dioxide as a waste product of respiration
Lactobacillus used in
Used in the production of yoghurt
How are microorganisms grown
On an industrial scale
In fermenters, with suitable conditions
Fermenters construction
Metal that won’t corrode due to acid waste
Special probes measure the contents
Fermenters PH
Kept constant by adding acid or alkali
Fermenters oxygen
Filtered air is added for respiration
Fermenters stirring paddles
Mixes the microorganisms with the nutrients, so they don’t sink
Helps keep the temperature event
Biotechnology
The use of living organisms to make useful chemicals and products
Fermentation
Reaction in yeast
When yeast retires it produces ethanol, the carbon dioxide produced makes bread rise
Yeast reaction
Glucose ——-> ethanol + carbon dioxide
